The CSN API provides APIs for the following functions:

API type API description
Cloud Smart Network APIs Provide APIs for Cloud Smart Network operations, including creating, querying, updating, deleting, and loading or unloading network instances.
Route management API Offer APIs for managing Cloud Smart Network routing entries, learning relationships, and association relationships, including their creation, deletion, and querying.
Bandwidth package APIs Provide APIs for bandwidth package operations, including creation, updating, deletion, querying, price inquiries, upgrading/downgrading, binding to Cloud Smart Network, and unbinding from Cloud Smart Network.
Cross-region bandwidth APIs Provide APIs for cross-region bandwidth operations, including creation, query, update, and deletion, ensuring smoother functionality.
TGW Provide APIs for querying the TGW list, updating TGW information, and retrieving TGW routing entries with ease.
